Cutting Bores Self Tapping Inserts In Stock

Cutting bores self tapping inserts(also known as self threaded inserts)are cylindrical metal bushings with internal and external threads and are specially designed to cut their own threads as they are being driven into a drilled hole, we have lots of this cutting bores self  tapping inserts in stock for shippment .

 


Short design : Works Standard 307


Long design : Works Standard 308


Features :

1. Self tapping insert has a large effective shearing surface, so ensuring a higher degree of pull-out strength.

2. Self tapping insert is driven subsequently into the finished work piece. This means a higher casting machine output, no rejects due to incorrectly cast-in insert components, no moulding sand trapped in the thread.

3. A pre-cast or pre-drilled retaining hole with normal tolerance requirements is sufficient for driving in the self tapping insert. The thread is always precisely positioned.

4. Self tapping insert is insensitive to small areas of shrinkage. The self tapping insert prevents damage caused by torn threads.

Manual Insertion Process


Manual installation with driving tool and tap wrench:

image

Emergency installation using screw and nut:

image


The manual insertion is usually carried out using the manual tool via the female thread or in case of the tools using the hexagon socket. You can of course also use power tools for the manual assembly. If doing so, it needs to be ensured that the rotatable sleeve is in the corresponding correct position.


Image 11.1/12.1

Thread the insert, cutting geometry (slit or bore) has to be pointing downward.Attention needs to be paid while doing so that the screw with nut does not face in the direction of the cutting geometry after locking with a counter nut, as the shavings are otherwise not discharged.


Image 11.2/12.2

Screw in the insert until approx. 0.1-0.2 mm underneath the surface of the work piece(during temporary assembly using screw and nut, the insert should be processed until flat). Vertical assembly must be ensured.


Image 11.3/12.3

Loosen the counter nut, otherwise the insert could possibly become unscrewed. Subsequently screw out the screw/screw-in tool.
